Numbers 18
3 Ref `And they have kept thy charge, and the charge of all the tent; only, unto the vessels of the sanctuary and unto the altar they do not come near, and they die not, either they or you;
4 Ref and they have been joined unto thee, and have kept the charge of the tent of meeting, for all the service of the tent; and a stranger doth not come near unto you;
5 Ref and ye have kept the charge of the sanctuary, and the charge of the altar, and there is no more wrath against the sons of Israel.
6 Ref `And I, lo, I have taken your brethren the Levites from the midst of the sons of Israel; to you a gift they are given by Jehovah, to do the service of the tent of meeting;
7 Ref and thou, and thy sons with thee, do keep your priesthood, for everything of the altar, and within the vail, and ye have served; a service of gift I make your priesthood; and the stranger who is coming near is put to death.'
8 Ref And Jehovah speaketh unto Aaron: `And I, lo, I have given to thee the charge of My heave-offerings, of all the hallowed things of the sons of Israel -- to thee I have given them for the anointing, and to thy sons, by a statute age-during.
